Katori Folk Arts Hontenかと里民芸店 本店

This shop in the corner of the sightseeing boat wharf sells live marimo and marimo goods. We recommend the jointly developed limited package marimo and kombu tea Marimochan in particular. The tea includes kombu in the shape of the protected marimo. They also have original T-shirts and stickers! The branch at Kosui is also worth a look.
